HomeRAB Pre-Cladding is a cost-effective robust rigid air barrier offering resistance to gusting winds to reduce draught and keep homes warm creating comfort inside. Each panel is engineered with a green water repellent sealer to keep moisture out, ensuring the panel remains dry.
The structural stability of fibre cement creates the strength and protection needed for meeting the bracing requirements of Very High wind zones, making it the perfect solution for residential buildings. James Hardie guarantee superior performance and peace of mind.
Rigid air barriers by James Hardie work by equalising the air pressure within the external wall cavity, making the building airtight providing superior weather-tightness, structural bracing and fire protection, whereas traditional flexible wall underlay can struggle to perform in these conditions.
HomeRAB Pre-Cladding is suitable for the exterior of almost all residential buildings including those in Very High wind zones. It is fixed directly to the framing and then vertical joints are sealed over the face.
HomeRAB Pre-Cladding is suitable for use behind all James Hardie claddings or alternative claddings such as brick, timber weatherboard and more.
In the opinion of BRANZ, James Hardie Rigid Air Barriers, if used, designed, installed and maintained in accordance with the statements and conditions of this Appraisal, will meet, or contribute to meeting the following provisions of the NZBC:
RAB Board is an Acceptable Solution rigid wall underlay material in terms of compliance with NZBC Acceptable Solution E2/AS1, Table 23.
This is an Appraisal of an Alternative Solution in terms of rigid wall underlay material for HomeRAB Pre-Cladding and an Alternative Solution installation method for both products in terms of the New Zealand Building Code compliance.
